From John Derbyshire:
“Every totalitarian power cult needs a vocabulary of vituperation—some way to talk about the enemies of the people: those wreckers, saboteurs, and counter-revolutionaries who are always trying to slow or divert society’s righteous march forward to a radiant future.”
Hence the current Congressional hearings about “White nationalism”.
Derbyshire aside, at first glance that site seems to have more than a whiff of ‘conspiracy theorists’.
